A reminder men hold me to (7)
I believe the answer is:
memento
'a reminder' is the definition.
(I know that memento is a type of reminder)
'men hold me to' is the wordplay.
'hold' indicates putting letters inside.
'men' placed around 'me' is 'memen'.
'memen'+'to'='MEMENTO'
(Other definitions for memento that I've seen before include "trophy" , "Souvenir, reminder of past event" , "Reminder of a person or event" , "might be kept for sentimental reasons" , "A reminder of death - . . . . . . . mori" .)
